SCREEN CAPACITY CALCULATION VIBFEM
depend greatly on the design of the screen, and most capacity formulas assume the screen design is correct for the application. This assumption is not always justified. A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reducedThere are different approaches to the modelling of the screening process. Probabilistic and kinetic models were one of the first attempts in the modelling of screening as a phenomenological process (Whiten, 1972) and (Ferrara and Perti, 1975). On the other hand, empirical or capacity models approach the screening process modelling byDiscrete element modelling of vibrating screens ScienceDirect
